    Bcm43xx-fwcutter or ndiswrapper

    Gateway MT6451 Laptop; bought used and came with Vista system restore disks - no thanks. Had heard good things about recent Ubuntu success with the Broadcom (4311) chipset for wireless.
    After full install of Kubuntu, used KPackage to update all packages and install ndiswrapper and the bcm 802.11 STA driver.
    Should I also install the "fwcutter" package?
    I'm not at home right now, so don't have access to the laptop in question (currently wired), but will try to get details about the bash responses pasted in later tonight.
    I was hoping this would "just work." Does re-starting help? Thanks in advance...

    Re: Bcm43xx-fwcutter or ndiswrapper

    b43-fwcutter finds and extracts the firmware needed to operate the native driver, b43. If ndiswrapper is installed correctly, b43-fwcutter is not needed. Let's troubleshoot your ndiswrapper install first.
    Code:
    sudo modprobe ndiswrapper
    ndiswrapper -l
    iwconfig
    I, or one of my highly experienced colleagues, will look for you tonight.

    Re: Bcm43xx-fwcutter or ndiswrapper

    Here you go. The first two bash entries just returned me to the prompt (no message - error or otherwise, no response):

    ian@Minnmax2:~$ sudo modprobe ndiswrapper
    ian@Minnmax2:~$ ndiswrapper -l
    ian@Minnmax2:~$ iwconfig
    lo no wireless extensions.

    eth0 no wireless extensions.

    ian@Minnmax2:~$

    What now, my friends?

    using the native broadcom drivers is probably the most trouble free method for the 4311.

    A quick alternative that seems to work for most people ( some not) can be found here using the sta driver

    Either way you may have to remove the ndiswrapper module.

    Any suggestions?

    I think it is time to look at the output of

    lsmod
    (LSMOD in lowercase)

    copy/paste the output back here so we can see what modules are loaded.

    Re: Bcm43xx-fwcutter or ndiswrapper

    Community Wiki Documents on Broadcom wireless drivers.
    Broadcom BCM43xx Chipset
    This page aims at getting your BCM43xx chipset based wireless network card to work in Ubuntu.
    Personally I've used
    Code:
    sudo apt-get install b43-fwcutter
    and it has worked each time.

    My wireless card (for reference)
    Code:
    $ lspci
    <snip>
    01:03.0 Network controller: Broadcom Corporation BCM4309 802.11a/b/g (rev 03)
    Unfortunately I haven't had the same luck with KDE as with Gnome, except for Fedora 12 (which saw the Broadcom out-of-the-box) but that was with previous versions of Ubuntu, not anything in the 9.'s
    Friends don't let friends wear a red shirt on landing-party duty.

    Re: Bcm43xx-fwcutter or ndiswrapper

    Seeing the above mentioned url it has a section labeled

    "Installing drivers for the BCM4311,4312,4321,4322 Cards

    ~$ sudo apt-get update && sudo apt-get install bcmwl-kernel-source"

    since your card is the BCM4311 this is the section I would follow.

    Re: Bcm43xx-fwcutter or ndiswrapper

    Thanks, all. I have confirmed that I have the "kernel-source" - everything seems right in that regard. I can't find any reference to "wlan0" so I'm thinking that Kubuntu is not recognizing my wireless card. (iwconfig and ifconfig only shows the eth0)
    The laptop is certainly not receiving any wireless signals. I have removed the ndiswrapper packages, and assume that the b43 driver is included in the stuff I downloaded from the Broadcom site (bcm 802.11 STA).
    I struggled with an old Linksys WMP54G adapter (also Broadcom) in my old Celeron desktop, and I'm kind of bummed that after five years of messing with these Broadcom wireless chipsets, no Linux distro has been able to figure it out, so that it "just works."
    I have gone through the threads referenced - I seem to be missing "wl" (?), but can't find a package that seems to provide it.
